Specification of Letters Patent.

Application filed September 2, 1905. Serial No. 276,832.

T0 all whom it may concern:

Be it known that I, HENRY ROBINSON, a citizen of the United States, and a resident of Brooklyn borough, city of New York, county of Kings, and State of New York, have invented a certain new and useful Improvement in Machines for Capping Bottles, of which the following is a speciiication.

, This invention has relation to an improvement in machines for fixing on the necks of bottles the well-known metal capsules on which trade-marks and other matter are ordinarily embossed or printed.

The invention is illustrated in a preferred form in side elevation'in the accompanying drawing, one of the supporting-arms being removed for greater clearness.

In the form of this invention which is illustrated the base ofthe device 1 carries a lower semicircular jaw 2, appropriately supported on the base by means of a rib 3 or any equivalent structure. The Asecond semicircular jaw 4 is carried by a lever 5, pivoted, as at 6, to the support 8, and the parts are so related that when the lever 5 is depressed the jaws 4 and 2 will iit together to complete the circle, as indicated in dotted lines.

The jaw 4 is normally held in the raised position shown in the drawing by a spring 7, which abuts upon an extension of the lever 5, which is adapted to move up and down between two arms extending u wardly from the support 3, one of which is s own at 8 and the other of which is removed to better disclose the structure. Between the upper ends of the arms 8 there is pivoted a lever 9, having a handle 10 at its outer extremity and provided with a rounded beak 11, one face of which lies against the u per face of the extension ofthe lever 5 when the device is in its o en position. (Shown in the drawing in full ines.)

At the base of the beak 11 there is provided a shoulder 12, which its against. the tip of the extension to the lever 5 when the device is in its open position. The tendency of the spring 7 is to throw the lever 5 ulpward and through the beak 11 to swing t e lever 9 backward in a direction op osite to that indicated by the arrows. Were this tendency is not resisted, the lever 9 and handle 10.are thrown too far over, Vand this movement might easily be carried to a point where the lever 5 would pass over the beak 11, thus preventing operation of the device when the lever is pulled to the right in the drawing. The shoulder 12, however, prevents the mishap above mentioned, since when the spring 7 brings the device into the position shown in the drawing further movement upward of the lever 5 and to the left of the lever 9 is prevented by the shoulder 12 coming in contact with the tip of the lever 5. rIhe shoulder 12 thus forms a convenient stop, which can be provided without extra labor, since it is cast in one piece with the lever 9` The operation of the device is as follows: The neck of the bottle with the capsule loosely on it is introduced between the aws 2 and 4 and the lever 9 is turned down into the position shown in dotted lines, causing the rubber linings 13 in the jaws 2 and 4 toiirmly com ress the capsule around the bottle. The ownward movement of the lever 5 is produced directly by downward rotation of the beak 11', which takes the position shown in dotted lines when the jaws 2 and 4 are closed. The adjustable screw stop 14 is carried by the lever 5 near its fulcrum in such a position that when the jaws are tightly closed the under side of the lever 9 comes against said stop and by transferring the point of application of pressure very close to the fulcrum makes it impossible for the most careless workman to exert by hand excessive or damaging pressure on the bottle-neck.

What I claim isi In a machine for compressing capsules, a pair of jaws pivoted to each other, a spring tending to open the jaws, a pivoted operating-lever, a beak on said lever making contact with the outer surface of one of said -aws and a stop-shoulder on said lever ma ng contact with the end of said jaw when the device is in its open position, substantially as described.

HENRY ROBINSON.
